Why Choose the Lovato P1MB1NC20 Miniature Circuit Breaker?

The Lovato P1MB1NC20 is a dependable miniature circuit breaker (MCB) engineered to protect low-voltage electrical circuits against overloads and short circuits. As part of the trusted Lovato Electric P1MB series, it combines reliable thermal-magnetic protection with a compact modular design suitable for commercial, industrial and OEM electrical installations.

With a 20 A rated current, Type C tripping characteristic and 6 kA short-circuit breaking capacity, the P1MB1NC20 is ideal for protecting circuits supplying equipment with moderate inrush currents, including lighting, small motors, transformers and power supplies.

Its 1P+N configuration provides overcurrent protection on the phase conductor whilst simultaneously switching the neutral conductor. The two DIN module design enables safe circuit isolation whilst allowing quick installation on a standard 35 mm DIN rail.

Key Advantages

  • Reliable overload and short-circuit protection for low-voltage electrical circuits.
  • 20 A rated current suitable for commercial and industrial applications.
  • Type C tripping characteristic accommodates moderate equipment starting currents.
  • 6 kA breaking capacity provides dependable fault-current interruption.
  • 1P+N configuration switches both phase and neutral conductors.
  • Thermal-magnetic operating mechanism for dependable circuit protection.
  • Compact two-module construction conserves panel space.
  • Quick installation onto a standard 35 mm DIN rail.

Key Features

  • Lovato Electric P1MB series.
  • 20 A rated current.
  • Type C tripping characteristic.
  • 1P+N pole configuration.
  • 6 kA short-circuit breaking capacity.
  • 230/400 V AC rated operating voltage.
  • 60 V DC rated operating voltage.
  • 440 V rated insulation voltage (Ui).
  • 4 kV impulse withstand voltage (Uimp).
  • DIN rail mounting with screw terminals.

Reliable Protection for Electrical Distribution Systems

The Lovato P1MB1NC20 combines thermal and magnetic tripping elements to protect electrical wiring and connected equipment. The thermal element responds to sustained overloads, whilst the magnetic mechanism provides rapid disconnection during high-current short-circuit faults, helping minimise equipment damage and downtime.

Its Type C characteristic makes the breaker suitable for installations containing moderate inductive loads where temporary start-up currents occur. This provides dependable protection without unnecessary nuisance tripping in many commercial and industrial applications.

Typical Applications

  • Commercial distribution boards.
  • Industrial control panels.
  • Lighting circuits.
  • Small electric motors.
  • Control transformers.
  • PLC and automation systems.
  • Building services equipment.
  • Machine control and auxiliary circuits.
